Translate Shutter Angle into Exposure Time for Each Shot
Shutter angle only becomes an exposure duration once frame rate is known. Convert both together before comparing blur across normal-speed and slow-motion shots.
1 · shot | frames per second | shutter angle degrees

Research prototype — checkout unavailable. Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the shutter exposure docket: your shot | frames per second | shutter angle degrees stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Retiming footage does not change the interval used when it was captured. After: the shutter exposure docket shows the working beside each named row so the reader can change the assumption and inspect the consequence.

- Method: Exposure milliseconds = 1000 ÷ frames per second × angle ÷ 360. At 24 fps and 180 degrees the interval is about 20.83 ms; at 60 fps it is about 8.33 ms.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.

Optional AI formatting, not calculation
For this shutter exposure docket, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a shutter exposure docket. Return plain rows only: shot | frames per second | shutter angle degrees. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: shot | frames per second | shutter angle degrees. No AI response is executed as code.
